CBS Radio

CBS Radio was a radio broadcasting company and radio network operator owned by CBS Corporation and founded in 1928, with consolidated radio station groups owned by CBS and Westinghouse Broadcasting/Group W since the 1920s, and Infinity Broadcasting since the 1970s. The broadcasting company was sold to Entercom (now known as Audacy, Inc.) on November 17, 2017. Although CBS's involvement in radio dates back to the establishment of the original CBS Radio Network in 1927, the most recent radio division was formed by the 1997 acquisition of Infinity Broadcasting by CBS owner Westinghouse. In 1999, Infinity became a division of the original Viacom; in 2005, Viacom spun CBS and Infinity Broadcasting back into a separate company, and the division was renamed CBS Radio.
